Description
The National Instruments PXI-4462 is a PXI Sound and Vibration Module that stands out in the realm of Dynamic Signal Acquisition (DSA) devices. It is identified by its part numbers 779688-01 and 779131-01, indicating its unique specifications and configurations within the DSA category.
This high-performance module operates with a 24-bit resolution, ensuring precise data acquisition for a wide range of sound and vibration analysis applications. It is capable of a sample rate of up to 204.8 kS/s, making it suitable for capturing high-frequency signals without compromising data integrity.
Equipped with four-channel dynamic signal acquisition, the PXI-4462 offers versatility for simultaneous measurement of multiple signals. This feature is complemented by six gain settings, allowing users to adjust the sensitivity of signal capture based on the specifics of their experimental or testing conditions.
A notable feature of this module is its high-pass filter cutoff frequency of 3.4 Hz, which is particularly useful in eliminating low-frequency noise and enhancing the quality of the signal analysis. Additionally, it supports both differential and pseudo-differential analog input terminal configurations, providing flexibility in connecting various types of sensors and transducers.
The analog overload point for 0 dB gain range is specified at 10.7 Vpk, ensuring robust performance even under high input signal conditions. Software compatibility is broad, encompassing LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, Borland C++, and Microsoft .NET, thereby offering seamless integration into a variety of development environments. The module is driven by NI-DAQmx software and can be configured using the Measurement & Automation Explorer (MAX) tool, simplifying setup and customization for specific application needs.
Despite being announced as obsolete by National Instruments, the PXI-4462 remains available for purchase and repairs through Apex Waves, ensuring that users can continue to leverage its advanced capabilities in their sound and vibration analysis projects.
